Not sure of the name/number/markings, but attached photos of broken part & closet doors (it is the "left" panel that is broken). Hope you can identify this item & look forward to hearing back as soon as possible.
Thank you.

Hi, Linda. That looks like a match for our 23-142 closet door guide. See the 23-141 for the opposite hand side, as well.
